Answer:
∠MKN = 30°
Step-by-step explanation:
∠PKL = 2x
∠MKN = x
2x + x = 90
3x = 90
x = 30
∠MKN = 30°
Call b the amount of babysitting hours and 5 the amount of gardening hours.
10b+5g=80
b+g=12
Subtract 5 times the second equation from the first to get:
5b=20
Thus, b=4. g=12-4, or 8. Therefore, Sarah spends 4 hours babysitting and the rest gardening.
8/12 is the answer bc 1/4 can be converted to 3/12 and with a common denominator you can now add and you’ll get 8/12
